Wildlife is an important secondary use of this soil. The cropland areas provide favorable habitat for ring-necked pheasant and mourning dove. Many nongame species can be attracted by establishing areas for nesting and escape cover. For pheasants, undisturbed nesting cover is essential and should be included in plans for habitat development, especially in areas of intensive agriculture. Rangeland wildlife, or example, the pronghorn antelope, can be attracted by developing livestock watering facilities, managing livestock grazing, and reseeding where needed. This soil has good potential for urban and recreational development. Increased population growth in the survey area has resulted in increased homesite construction. The chief limiting soil feature for urban development and road construction is the limited capacity of this soil to support a load. Septic tank adsorption fields function properly, but community sewage systems should be provided if the population density increases. Because of the permeability of the substratum, sewage lagoons must be sealed. Lawns, shrubs, and trees grow well. Capability subclass Ile irrigated, IVe nonirrigated; Loamy Plains range site. Nunn clay loam, 0 to I percent slopes This is a deep, well drained soil on terraces and smooth plains at elevations of 4,550 to 5,150 feet. It formed in mixed alluvium and eolian deposits. Included in mapping are small, long and narrow areas of sand and gravel deposits and small areas of soils that are subject to occasional flooding. Some small leveled areas are also included. Typically the surface layer of this Nunn soil is grayish brown clay loam about 9 inches thick. The subsoil is light brownish gray clay loam about 14 inches thick. The upper part of the substratum is clay loam. The lower part to a depth of 60 inches is sandy loam. Permeability is moderately slow. Available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is slow, and the erosion hazard is low. This soil is used almost entirely for irrigated crops. It is suited to all crops commonly grown in the area, including corn, sugar beets, beans, alfalfa, small grains, potatoes, and onions. An example of a suitable cropping system is 3 to 4 years of alfalfa followed by corn, corn for silage, sugar beets, small grains, or beans. Few conservative practices are needed to maintain top yields. All methods of irrigation are suitable, but furrow irrigation is the most common. Barnyard manure and commercial fertilizer are needed for top yields. Windbreaks and environmental plantings of trees and shrubs commonly grown in the area are generally well suited in this soil. Cultivation to control competing vegetation should be continued for as many years as possible following planting. Trees that are best suited and have good survival are Rocky Mountain juniper, eastern redcedar, ponderosa pine, Siberian elm, Russian-olive, and hackberry. The shrubs best suited are skunkbush sumac, lilac, Siberian peabush, and American plum. Wildlife is an important secondary use of this soil.
